Queen Elizabeth II becomes world's second-longest reigning monarch

London: Britain's Queen Elizabeth II on Sunday overtook Thailand's King to become the world's second-longest reigning monarch in history, after France's Louis XIV.

The UK has been celebrating the 96-year-old Queen's Platinum Jubilee to mark 70 years of service to the nation with grand events taking place last weekend.

Now she has overtaken Thailand's King Bhumibol Adulyadej, who reigned for 70 years and 126 days between 1927 and 2016, to set another record. Louis XIV of France remains the longest-reigning monarch, with a 72-year and 110-day reign from 1643 until 1715.

Crowned in 1953, Queen Elizabeth II became the longest-serving British monarch in September 2015, surpassing her great-great grandmother Queen Victoria.

After four days of royal parades, street parties, pageantry and other events held across the UK and the Commonwealth to mark the Platinum Jubilee milestone, the monarch thanked the nation in a letter, saying that she had been "humbled and deeply touched", and that "this renewed sense of togetherness will be felt for many years to come".

The Queen has been hit with some age-related mobility problems and chose to miss some of the events, with her son and heir Prince Charles and second in line Prince William and close ranks of the royal family joining. She did appear on the balcony of Buckingham Palace at the end of the Jubilee Pageant as the extended Bank Holiday weekend drew to a close.
